Title: Semiconductor devices and methods for assembling them
Inventor: WEIMAN IRVING
IPC: H01L23/04
Filed: 1960-01-06
Abstract: 928,110. Semi-conductor devices. PACIFIC SEMICONDUCTORS Inc. Jan. 6, 1960, No. 512/60. Class 37. A method of assembling a semi-conductor device which allows the semi-conductor element to be etched before it is encapsulated comprises the steps of electrically connecting one surface of a semi-conductor crystal to a first electrode, joining the first end of a lead element to another surface of the crystal, sealing the first electrode within one end of a tubular envelope, and providing, at the other end of the envelope, a second electrode, which is soldered to the second end of the lead element. In the diode shown in Fig. 2, a crystal 10 of, e.g. N-type Si, having a diffused P-type region 13 at one surface, is soldered at the opposite surface to an electrode 12, and one end of a resilient lead element 14 of, e.g. S- or C-shaped Mo wire, is bonded to the P-type region 13. This sub-assembly is inserted in one end of a tubular envelope 20 comprising a tube 23 of ceramic or glass into the ends of which are fused metal sleeves 21, 22. A second electrode 15 is inserted in the other end of envelope 20, the free end of lead 14 being received in a hole 16 in the end of electrode 15 containing a piece of solder 17. Sleeves 21, 22 are welded to electrodes 15, 12 respectively, the heat generated thereby also effecting the soldering of lead 14 into hole 16. In a modification, the lead 14 is shorter and is soldered into a hole in one end of a thicker lead which is in turn soldered into a bore in electrode 15. Fig. 3 shows a transistor comprising an N-type base region 33 bonded to a metal flange 34, and P-type emitter and collector regions 31, 32, to each of which is connected a lead 37, 36. A glass envelope is in two parts 23a, 23b, each part having a metal sleeve fused into it. The flange 34 is fused between the two parts of the envelope and electrodes 40, 41 are added as described above. Alloy junction devices may be used. Semi-conductor materials mentioned are Ge, Si, Ge-Si alloy, InSb, AlSb, GaSb, InAs, AlAs, ZnS, GaAs, PbS, PbTe, PbSe, CdS, CdTe, CdSe; donor impurities ; Sb, As, Bi, P, or any other element of Group V of the Periodic Table; and acceptor impurities: In, Ga, Tl, B, Al, or any other element of Group III of'the Periodic Table.

Title: Improvements in air pressure brakes
IPC: B60T15/54
Filed: 1929-01-07
Abstract: 306,121. Rihosek, J., Leuchter, R. L. and Hardy Maschinenfabrik und Giesserei Akt.-Ges., Geb. Feb. 17, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Addition to 260,250. Fluid-pressure.-The valve device for effecting the graduated release of single chamber compressed air brakes described in the parent Specification is modified by the provision of a non- return valve between the auxiliary reservoir and the piston chamber of the release valve and of a working surface for the release valve which is subject to the brake cylinder pressure whereby the valve is controlled by the initial auxiliary reservoir pressure, and by the variable train-pipe and brake cylinder pressures. The system comprises a main control valve 33, a graduated release valve 1 and a valve 13 which normally cuts off the train-pipe 30 from the valve 1 in running conditions. In running conditions the parts occupy the position shown in which the train-pipe 30 is connected to the main valve 33 by pipe 14 and to the chamber 21<1> of the valve 13 by pipe 50. The auxiliary reservoir 39 is connected to the release valve chamber 7<1> through a non-return valve 83 so that the pressure in this chamber is maintained at the initial pressure in the auxiliary reservoir. The brake cylinder B is connected through the main valve 33 to the chamber 19<1> of the valve 13 and thence to the atmosphere by the port 17. When the trainpipe pressure is increased after an application of the brakes, the brake cylinder pressure acting on the piston 19 lifts the valve 21 so that the trainpipe pressure acts beneath the piston 7 and together with the brake cylinder pressure acting beneath the valve 80 overcomes the initial auxiliary reservoir pressure acting above the piston to lift the valve 80 and permit exhaust of the brake cylinder to an extent dependent upon the increase in train-pipe pressure. The port 17 is kept closed by the piston 19 as long as the brake cylinder pressure is high enough to hold this piston in the raised position.

Abstract: 545,205. Belt fastenings. ZILLER, H. J. Jan. 16, 1941, No. 631. Addition to 509,978. [A Specification was laid open to inspection under Sect. 91 of'the Acts, Feb. 3, 1941] [Class 80 (i)] The parent Specification describes a belt fastening comprising a V-shaped member, made from flat sheet or strip, having its shanks disposed on opposite sides of the belt one of the shanks terminating in a pointed hook adapted to be driven into the belt fabric and the other in an eye adapted to receive the pointed end and to bend the same so that after passing through the eye the hook becomes self re-entrant into the belt. According to the invention such hooks are made of wire. The wire hook 1, Fig. 1, has a pointed end 2 adapted to enter an eye 3 formed in the other end by flattening or deforming. When clinched by the presser jaws 5, Fig. 4, the point is bent over the rim of the eye into the belt in the direction away from the edge thereof. For this purpose the jaws are provided with guiding surfaces 6. In modifications (1) the eye is slightly off-set by bending the wire (2) the eye may be elongated and be formed by twisting the wire, Fig. 7, the parallel parts 12 producing a groove to guide the point into the eye 11 (3) this groove may be formed by a roof-shaped surface, (4) the eye 16, Fig. 9, may have two perforations 18, 19 through which the point 20 passes, (5) the eye has a transverse wedge-shaped bar 26, Fig. 10, adapted to separate the parts of the split pointed end 23, (6) the parts of the split pointed end may be bent over transversely to the line of the belt, Fig. 11 (not shown).

Filed: 1944-01-15
Abstract: 574,205. Weighing-apparatus. SHOOSMITH, G. T. Jan. 15, 1944, No. 805. [Class 143] In weighing and pressure indicating or recording apparatus in which the load or pressure is transmitted hydraulically to a piston &c. acting on a steel-yard which is loaded by a plunger immersed in a heavy liquid, the effective weight of the plunger is made to depend on the extent of its immersion which varies with the load or pressure being measured and the corresponding position of the steelyard. As applied to a crane, the hoisting rope passes round a pulley connected to the piston of a hydraulic cylinder communicating by a pipe to an inlet k beneath a plunger h. The plunger h acts through a link n upon a lever o carrying a lead-filled container r dipping into mercury. A rack t actuates the indicating pointer w. In use, the load on the crane generates a pressure at the inlet k and the plunger h moves the balance lever upwards until the displacement of the container r balances the thrust. A cup z attached to the container r damps oscillations. Totalizing and/or recording mechanism may be provided in addition to or instead of the indicating pointer. A reservoir and hand pump are provided for adding working fluid to the system. The container may be varied in cross-section to enable equal increments of load to cause equal movements of the pointer.
